Animation: Harmonic relationships in the planetary system HD 110067
All six planets orbiting the star HD 110067 have orbital periods that are in 'whole-number ratios' to one another. This results in resonances that are known in music as fifths (3:2) and fourths (5:4). For example, the orbital resonances between the planets HD 110067 b and c, c and d, and d and e are each 3:2 – known musically as a fifth, and between the planets e and f and f and g are each 4:3 – which corresponds to a fourth. In this animation, the planet's orbits and sizes are shown to scale relative to each other, but not relative to the size of the star. The long yellow band indicates the transit region, where a dip in light from the star can be observed from Earth as each planet passes in front of HD 110067. The pitch of the notes played as each planet transits corresponds to the resonant change in orbital frequencies between each planet.
